Windows 11 Insider Preview Build 25381 lets users easily fix webcam errors

Microsoft is diligently working on enhancing Windows 11’s reliability. The tech titan is testing new things through Windows Insider Preview Program. Yesterday, we have seen a couple of new editions come with the latest dev preview build. And today, Microsoft has released a new Windows 11 Insider Preview Build 25381 for the Canary channel.

Today’s release is mainly focused on fixing known issues and rolling out with Windows 11 Insider Preview Build 25381.1000 (rs_prerelease) build number. Obviously, it is a small upgrade that you can quickly install on your PC if running on a Canary build.

Microsoft didn’t mention the complete list of changes and fixes in the release notes for Canary builds, but they do mention some major fixes. So, today’s release mainly addresses two issues reported by Windows 11 users, including the camera streaming issues and SMB signing requirement changes.

As per the details, SMB signing is now required by default for all connections on Windows 11 Insider Preview Build 25381 Enterprise editions. This change overwrites the legacy behaviour where SMB signing was required only when connecting to shares named SYSVOL and NETLOGON and where Active Directory domain controllers. You can explore complete details about the change by navigating to the Windows Insider Blog.

The second change that comes with today’s release is the improvements coming to the webcam, the changelog hints if the camera fails to start, then you will see a popup dialog with the recommendation to launch the automated Get Help troubleshooter to resolve the issue.

If your PC is running on Windows 11 with the Canary channel in Windows Insider Preview Program, then you can install the new release preview build on your system. You can check for the new update by visiting Settings > Windows Update > Check for updates.
